ABSTRACT
This chapter traces some of the major variables at the macro-level which have influenced labour migration rates in Rhodesia. It considers certain problems which arise in analysis when, as sociologists, to consider data at the micro-level. The chapter suggests that a significant improvement in analysis at this level can be obtained by applying a 'decision-model'. In searching for a more adequate model for understanding circulatory migration it might be useful to review briefly two orientations which have been applied to the understanding of social processes in general: these may be designated briefly as the 'institutional' and the 'statistical'. Blau et al. have argued, in relation to occupational choice, that by applying a decision model at crucial turning-points in the lives of individuals, it is possible to analyse the effects of a succession of earlier decisions on the final choice of occupation.
